Extension tubes open up a whole new world!

With travel photography, one of the issues is prioritising equipment. You simply can’t carry everything you could possibly want to bring. If you do then it often hampers the overall travel experience as you’re weighed down by equipment and have to constantly look after it. For me, on my current trip that meant I couldn’t justify bringing a dedicated macro lens, especially when I had the XF56mm and XF50-140mm covering the similar focal lengths offered by the two available macro options. Instead I chose to pack both the 11 and 16mm extension tubes (MCEX-11 / 16). Offering camera-lens communication that allows autofocus, these simple compact devices can turn nearly any lens into a macro option (but please check lens compatibility).

My primary role in Costa Rica is to work as a researcher for a scarlet macaw program, so macro functions weren’t really at the top of the list. However the wildlife in this region is remarkable and macro functionality quickly became important. One of the sites we regularly see is a trail of leaf cutter ants marching through the forest taking supplies from the canopy to their nest. Following the tiny motorway, which has been carved out of the rainforest floor you’ll eventually find yourself at the base of a tree that’s being harvested.

Although I am focusing on leaf cutter ants, the general principles apply to all types of macro photography.

It is possible to get macro photos with wide apertures, these were taken at F4 with the XF50-140mm and X-T1, using ISO 3200(!) because the rainforest undergrowth was so dark (ominous clouds were gathering) and the ants were moving so fast, I needed fast shutter speeds, 1/600, 1/400 to help freeze the motion as I wasn’t using any flash.

Macro Photography fundamentals

For this type of photography you generally want to be using very high F Stops e.g. F22. The reason for this is when you start to focus on very close objects; the depth of field becomes very thin with more regular F Stops like F4, 5.6, 8. Even the maximum aperture on your lens is often not enough to get most of the frame sharp. One technique employed is to focus stack. Taking multiple pictures of a static subject, moving the focus throughout the frame and then stacking the pictures in postproduction. This wasn’t an option for me unfortunately as the ants were moving continuously (so fast when you’re looking at a macro frame!).

Using flash helps to stop these fast moving insects in their tracks. Note that the bokeh does degrade because of extension tubes. Taken with X-T1, XF50-140mm and stacked extension tubes. I used a Nissin i40 to light the scene from just above the camera.

Extension tubes – what are they?

They are simply extensions of the lens barrel, extending the distance between the rear lens element and the sensor. This shifts the focus, so for example instead of focusing at over 10 metres according to the lens, you’re actually focused 0.5 metres away when using an extension tube. There are two extension tubes available from Fujifilm a 11mm and 16mm. This gives you three options as you can stack the two together. The greater the distance, the closer the focusing.

Some lenses have very close native focusing distances

There are non-macro focused lenses that do actually have very close minimum focusing distances. For me, the two lenses spring to mind – the XF10-24mm and XF16mm. Though not particularly helpful for ‘normal’ macro photography because of they’re wide-angle lenses. However, I really like using both of these lenses for placing my subject within its environment, the benefit of these two is that my subject can be an elephant or an ant, both lenses are capable.

Downsides to extension tubes?

Well as you might have seen on some of the images, the bokeh can regress from the wonderfully smooth circles we are all used to from Fujifilm lenses, to something more like heptagon! The high image quality we are also used to does degrade somewhat, but this is to be expected when you’re pushing a lens from what is designed for. What you have to remember is that these are ultra lightweight, convenient macro inducers that save you money and carrying around another lens.

I am only touching the fringes of what is possible with macro photography, there are many out there who know a lot more about macro, but the benefit of extension tubes for those on the go is obvious.

Macro Creativity

With a little time and patience you can really start to create some interesting images. Though the images below are nothing particularly new, it was nevertheless satisfying to produce them. Using an off camera flash, placed behind the ants shooting back towards the camera backlights the ants and produces some interesting silhouettes/shadows thanks to the leaf cuttings.

I hope this has been helpful. Here is a short video of how I went about creating these images. Filmed and edited by Ellice Dart. If you liked this blog and video then please leave a constructive comment below.

Very nice article and great photos. I was a Canon shooter before jumping into Fuji a few years ago. I never tried the Canon extension tubes, but The Fuji tubes are starting to look very nice. I’ve never shot macro before, but have a project coming up where I will have need. I don’t want to go out and buy a macro lens, so these tubes might be the next best thing.

Ben, this is so helpful. I am going to Costa Rica in a few weeks and am new to macro photography. I have a Fuji X-T100. Your article has convinced me to go ahead and buy the extension tube. Hopefully, the trip will provide some memorable photos. Do you ever use the macro lens filters with the extension tube?
